# The latest POSIX draft (d5) allows either behavior. It says:
#
# For regular files, for each bit set in the octal number
# corresponding to the set-user-ID-on-execution or the
# set-group-ID-on-execution, bits shown in the following table shall
# be set; if these bits are not set in the octal number, they are
# cleared. For other file types, it is implementation-defined whether
# or not requests to set or clear the set-user-ID-on-execution or
# set-group-ID-on-execution bits are honored.
# FIXME: consider changing GNU chmod to work like other versions of chmod.
# For now, this test simply confirms the existing behavior.
